Real-time billing system for a call processing system

摘要

A system and method for processing telephone calls and providing enhanced services is presented. The call processing system includes a billing system that processes billing information records for completed calls. The billing system applies rate information stored in a rate file to the completed call parameters contained within the billing information record. Derived billing information is subsequently stored in a toll file. The billing system also uses rate information stored in the rate file to respond, in real-time, to rate quote requests. Upon receipt of a rate quote request from a requesting system, the billing system retrieves rate information from the rate file, calculates a cost/minute of a desired call, and returns a rate quote to the requesting system.
